A rectangle has a length of 3x + 7 and a width of 2x. If the perimeter of the
Art [367]

Answer:

The length of the rectangle is 31.

Step-by-step explanation:

We have that the length (L) and width (W) are:

L = 3x + 7

W = 2x

The perimeter of the rectangle is given by:

P = 2W + 2L

94 = 2(2x + 3x + 7)

94 = 10x + 14

x = 8

Now, we can calculate the length of the rectangle:

L = 3x + 7 = 3*8 + 7 = 31        

         

Therefore, the length of the rectangle is 31 units.

I hope it helps you!

A radio transmission tower is 170 feet tall. how long should a guy wire be if it is attached 15 feet from the top and is to make
beks73 [17]
The image of the given scenario is attached below.

A right angled triangle is formed, with one angle equal to 27 degrees. The perpendicular side is 155 and we are to find the length of guy wire which makes the hypotenuse of the right angled triangle.

Using the formula of sine, we can write:

sin(27)= \frac{155}{x}  \\  \\ 
x= \frac{155}{sin(27)} \\  \\ 
x=341

Rounding to nearest whole number, the length of the guy wire that must be attached is 341 feet.

The perimeter would be ≈ 36.797836892947.

Rounded would be about 37, or 36.8.

Hope this helps!!!!

P=4a

d\sqrt{2a}

Solving for P:

P=2\sqrt{2d} =2*\sqrt{2*13.01}≈36.79784
